An airplane flies at an altitude of y = 4 miles toward a point directly over an observer (see figure). The speed of the plane is 700 miles per hour. Find the rates at which the angle of elevation 0 is changing when the angle is 0 = 30°, 0 = 60°, and 0 = 70°. (a) 87.6 8 = 30° (b) 8 = 60° 151.56 Not drawn to scale X rad/min y mi. X rad/min 8 = 70° (Round your answer to two decimal places.) 154.53 X rad/min
